NIWeek 2011 Embedded Systems Recommendations

2011-07-26T00:54:00.016-05:00

'tis that time of year again, to prepare for NIWeek, peruse the conference program and come up with a list of sessions to attend. In order to get your list started, following are my recommendations of events and sessions that will be of interest to embedded systems developers. These sessions focus on developing reliable and robust embedded applications using NI's LabVIEW Real-Time and FPGA platforms, including CompactRIO. Most of the sessions I recommend are at the intermediate level with a few advanced level session mixed in. I have included the complete abstract for all sessions at the end of this post, and they can also be found in conference program.

In addition:

Make sure to tour the demos in the exhibition hall to learn about the latest greatest products and our partners
Take advantage of the chance to talk directly to tons of NI engineers throughout the conference - lunch is a great time for this
If you don't have a session of interest on Tuesday, trek down to the other end of the convention center to room 3 for The Future of System Design Symposium. Check the program for details.
Have fun.

NIWeek 2010 Recommendations: How to compress 8 weeks into 3 days

2010-07-27T21:32:00.008-05:00

If you were to attend all of the listed sessions (not even counting Keynote presentations, counting meetings with developers, time spent in the Expo hall, the Technology Theater, the conference parties, etc.) it would take you roughly eight work weeks to see them all. Of course your boss won’t let you come to Austin for two months to learn all this great stuff, so we have to compress it into three days.

Here’s some of my recommendations for specific sessions to see if you’re working on industrial and embedded control or monitoring applications. Of course this is just a short survey and there are lots more great sessions on the schedule. In a few cases I recommend more than one session in a time slot. I couldn't decide, so I will let you make your own choice.

Unicode and LabVIEW

2010-03-17T23:18:00.004-05:00

Ever wanted to build a LabVIEW application and localize it to many different languages? Maybe even change the language while the application is running?

You have probably been told that LabVIEW doesn't support Unicode. Well that is not quite true. While Unicode is not an official feature of LabVIEW, it is fairly well supported in an unofficial manner. I have collected some VIs and tips on using Unicode in LabVIEW and posted them on NI Community.

Please check them out and post your comments.

LabVIEW OOP Singleton Reference Example

2010-01-19T09:53:00.001-06:00

If you use LabVIEW classes in your application, examples, POCs, etc., you may have been wondering how to implement a singleton object.

What is a singleton? Singletons are known in the LabVIEW world as action engines, functional globals with methods, and under a few other names. Basically it is a set of data with associated functions, and you ever only one instance of this object in your application. A functional global (non-reentrant subVI), with uninitialized shift registers (USR)) to store the data and multiple cases to implement the different functions, is the most common example of a singleton in LabVIEW. Using OOP you can easily create a class which contains the same data and functions, however, by default a class will not limit the application to only one instance (object) of the class.

There recently was a good discussion on LAVA about singletons, including a good reference example of a singleton implemented as a LV class provided by LV R&D.

http://lavag.org/topic/11513-singleton-design-pattern/page__view__findpost__p__70428

One application of a singleton object may be a database interface in an application where many different components or other objects access the same database. Typically you only want one object or component touching the database to avoid conflicts, race conditions, etc. A database access class with a singleton object is a good solution for this type of application.

My first go at writing a blog failed miserably after the first post. But as the saying goes, Try Try again. So here is my blog, Take 2.

I'm glad to say the xCE project, which I mentioned in my first post, has been completed very successfully, albeit not by me. It will be posted in the next few days on NI Developer Zone and I will write about it in an upcoming post. Search for it on ni.com in the mean time.

My time in the last few months has been occupied coordinating an update to the Machine Control Reference Architecture which we will publish for NIWeek. As part of this project I have updated the Queued Message Handler (QMH) design pattern and extracted the messaging piece into a separate Asynchronous Message Communication (AMC) reference library. It can be used to pass a variety of messages (commands, faults, alarms, status updates, etc.) between different parts of a LabVIEW application, including different LabVIEW targets connected by Ethernet.

My other area of focus recently has been deployment and replication of applications on the LabVIEW Real-Time and LabVIEW Touch Panel targets. I will be discussing this topic during NIWeek on Tuesday and will also be publishing a LV RT Application Deployment Utility reference application.

Going forward here I plan on highlighting and discussing different reference designs developed by the Systems Engineering group at NI and will throw in other random LabVIEW design and architecture topics.

If you see me at NIWeek, come say Hi. I'd love to talk with you about your applications.

Welcome to my Life on the Wire.

I'm not sure yet what aspect of LabVIEW life I want to document and comment on, but I figure I need to start where I am and then decide where I am going depending on the road ahead, my feelings of the day and possibly the weather out there in cyper space. Welcome and feel free to send me comments, feedback, and topic ideas that you're interested in.

I think my first direction will be to discuss my lack of knowledge of LVOOP and experience in learning/using LVOOP to implement a flexible and customizable configuration tool for LV applications (code name 'xCE'). I'm starting with the basic idea of the Tag Configuration Editor (TCE) and looking to expand it to handle more complex configurations (hierarchy, collections, etc.) and in addition enabling the developer to easily customize and configure their configuration editor by defining new item types using LVOOP. TCE for any configuration task => xCE.
